' T0 aZZ whom it ntay concern:

Be it known that I, MONROE GUETT, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inHandles for Electric Snap-Switches, of which the following is aspecification.

This invention relates to a handle whic has a yielding stem forattachment to the spindle.

The object of this invention is to provide a handle consisting of partsthat are simple to construct and easy to assemble and which will connectthe handle firmly to the spindle with the necessary elasticity forproperly holding the switch cover or plate in position.

This invention resides in a handle of insulating material having a yokeso embedded within it that the inner edges of the legs of the yokeextend into the socket and receive the notched head of the stem and theplate which holds the spring under tension upon the stem.

Figure 1 of the accompanying drawings shows a vertical transversesection of the handle. Fig. 2 shows a vertical longitudinal section ofthe handle. Fig. 3 shows a horizontal section, looking downwardly, onthe plane indicated by the dotted line 3 3 of Fig.

Fig. 4 shows a view of the handle looking upwardly from the bottom, andFig. 5 shows a plan of the plate.

The handle 1 may be formed to the desired shape of any suitableinsulating material, preferably a molded composition. A yoke 2 is soembedded within the insulating material of the handle that the inneredges of its legs extend into the socket. It is preferred to stamp thisyoke from thin metal with perforations, so that the insulation whenmolded will flow through the openings and hold the yoke firmly in place.Notches 3 are made in the inner edges near the ends of the legs of theyoke.

The stem 4, which is threaded to receive the ordinary switch-spindle,has a head 5, which fits the socket in the insulating material. Notchesare cut in the edges of the head, so as to receive the inner edges ofthe legs of the yoke when the stem is thrust into the socket. The wallsof these notches engage with the edges of the yoke, so that the stem,while free to move longitudinally, will rotate with the handle. Thespring 6 is placed upon the stem, and then the plate 7 is thrust uponthe stem, so as to hold the spring compressed between the head of thestem and the plate.

The plate is shaped to fit the socket and has notches 8, which receivethe inner edges of the legs of the yoke and allow the plate to be pushedinto the socket as far as the notches in the yoke. After the plate hasbeen pushed on the stem as far as the notches in the yoke it is rotatedso the edges of the plate will pass into the notches. It is preferred tostamp pockets 9 in the plate, so that when it is turned sidewisesufficiently the pockets will receive the outer walls of the notches inthe legs of the yoke. hen the plate is turned to this position, thespring thrusts it outwardly and holds it so that it will not get I outof position. In order to remove the mechanism from the interior of thehandle, the plate may be pressed inwardly slightly and turned until. thenotches are opposite the yoke-legs, and then the plate will slip off andallow the stem and spring to be removed.

The invention claimed is- 1. A handle for an electric snap-switch havinga body of insulating material with a socket, a yoke with notches in itsinner edges embedded within the insulating material and having its inneredges extending into the socket, a stem having a head that fits thesocket and notches that fit the inner edgesof the yoke, a spring on thestem, and a plate held in the notches in the inner edges of the yoke,substantially as specified.

2. A handle for an electric snap-switch having a bodyof insulatingmaterial with a socket, a yoke with notches in its inner edges embeddedwithin the insulating material and having its inner edges extending intothe socket, a stem having a head that fits the socket and notches thatfit the inner edges of the yoke, a spring on the stem, and a plate heldin the notches in the inner edges of the yoke and having notches in itsedges that allow it when a yoke With notches in its inner edgesembedturned to be removed from the notches in the a spring on the stem,and a plate that fits 1o yoke, substantially as specified. the socketand has notches that fit the edges 3. Ahandle for an electricsnap-switch havof the y0ke,.and pockets that are adapted to inga bodyofinsulating material withasocket, receive the outer Walls of the notchesin the I yoke, substantially as specified. ded Within the insulatingmaterial and havl MONROE GUETT.
